ABSTRACT

A bag ( 10 ) of thin plastic material shaped into a container having a closed end ( 11   b ) and an open end ( 11   a ) cut to provide two tying portions ( 18 ), and gusseted sides ( 14 ) extending between the open and closed ends. The plastic material is of a color and has embedded fragrance and antimicrobial agents, and has an imprinted design or pattern. The bag ( 10 ) is of a size suitable for receiving a single product, such as a used feminine hygiene product, along with any other material in the use or replacement of such product by a user, in which the tying portions ( 18 ) are tieable to seal said product within the bag. When a product is sealed in the bag ( 10 ) by a user, the antimicrobial agents inhibits the growth of odor causing bacteria, the scent masks any odors, and the color and imprinted design assists to conceal or obfuscate any blood on a used feminine product when received within the bag ( 10 ).

This application claims the benefit of priority to U.S. Provisional Patent Application No. 60/731,387, filed Oct. 28, 2005, which is herein incorporated by reference.

FIELD OF THE INVENTION

The present invention relates to a disposable bag for hygienic disposal of a feminine hygiene product, and relates particularly to an antimicrobial, scented, colored, imprinted bag for storing and then disposing of a used feminine hygiene product. The bag provides clean, easy and discreet disposal of such feminine hygiene product (e.g., pads, tampons, sanitary napkins, and panty liners). The bag may also be used for disposal of other individual products, where hygienic discreet disposal is desired, such as a used adult incontinence product. The present invention also provides a method for hygienic disposal using such bag, and a portable dispenser for the bags.

BACKGROUND OF THE INVENTION

Plastic scented films in the form of long tubes have been used for disposal of diapers in stand-along units, such as the Diaper Genie by Playtex Products of Westport Conn., USA, in which the tube is dispensed from a container in the unit and then drawn and twisted by the user between used diapers to minimize odors there from. When the unit is full, the tube and diapers individually captured therein are disposed of.

Other units have been developed for disposal of sanitary napkins and tampons, such as the Sanitary Disposal Unit manufactured by SDU of Australia, which has a liner bag which is compressed by the user between inserted sanitary napkins and/or tampons. The user is instructed to first wrap the used product in toilet paper or a wrapper prior to insertion in the Sanitary Disposal Unit. When the unit is full, the bag is removed for disposal and replaced with a new bag. Such bags in the Sanitary Disposal Unit are scented and have anti-bacterial characteristics, and are large enough to store in the unit up to 15 sanitary items. Thus, these bags are not practical for separate use outside of a Sanitary Disposal Unit for discreet personal disposal of an individually used feminine hygiene product, as they are too large and bulky for such purpose. Moreover, such units for storing sanitary items are not typically present in public bathrooms, rather often a container with a hinged lid is present for disposing used items, and as a result such container can become unsightly when opened, unsanitary, and can leak odors. Thus, a small discreet bag is desirable for disposal of a used feminine hygiene product that is available from stall mounted dispenser units or easily portable in a purse or handbag, and especially bags which are scented, sealable, and anti-microbial to resist growth of odor causing bacteria. Furthermore, such a small discreet bag when sealed may be disposed in normal trash bins, thus avoiding the expense of providing, cleaning, and maintaining separate disposal containers specially for used feminine hygiene products in public bathrooms, and avoiding clogged plumbing and waste-water pollution when used feminine hygiene products are improperly disposed in toilets.

Scented purple bags are sold by CeDo Ltd. of Telford, Shropshire, UK under the names Pop-ins or Ladymate for disposal of used feminine hygiene products. However, these bags despite tying portions are not anti-microbial, and thus after receiving a used feminine hygiene product can become odorous. Also, these bags can become unsightly, as their colored plastic material is practically see-through and do not sufficiently conceal used feminine hygiene contents. Thus, it would further be desirable to provide a small discreet bag that is in addition to being anti-microbial to resist growth of odor causing bacteria assists in concealing bag contents to the human eye.

SUMMARY OF THE INVENTION

Accordingly, one feature of the present invention is to provide an antimicrobial, scented, colored disposable bag for a used individual feminine hygiene product that can be easily sealed to contain such product therein, which can also be used for individual hygienic disposal of any other used product, such as an adult incontinence product.

Another feature of the present invention is to provide an antimicrobial, scented, colored disposable bag for hygienic disposal of a used product, which has an imprinted design that in addition to bag color assists to conceal or obfuscate from view, any unsightly blood on a used feminine product when received within the bag.

A further feature of the present invention is to provide antimicrobial, scented, imprinted, colored disposable bags that can be located in a dispenser for single bag dispensing therefrom.

A still further feature of the present invention is to provide antimicrobial, scented, imprinted, colored disposable bags that are small and discreet for disposing a used individual hygiene product.

Briefly described, the present invention embodies a bag of thin plastic material having a closed end and an open end cut to provide two ending tying (or handle) portions, and gussets allowing for expansion along the sides of the bag extending between the open and closed ends. The plastic material is of a color (e.g., pink), and has embedded fragrance (or scent) and antimicrobial agent(s). When a product is placed in the bag by a user, the tying portions are knotted to seal the bag close with the product inside, in which the antimicrobial agents inhibits the growth of odor causing bacteria, the scent masks any odors, and the color assists in concealment of contents in the bag.

The bag may be imprinted with a design or pattern. The imprinted design, and the selected bag color (e.g., pink) and the color of the imprint (e.g., darker reddish pink color) assists to conceal or obfuscate blood on a used feminine product when received within the bag. Also, the bag may be of a size limiting such bag to receiving only one used product along with any other used material typically present in the use or replacement of such product by the user. Such material in the case of a feminine hygiene product may be for example, a wrapper, or a plastic or cardboard inserter or applicator.

When the bag contains a used feminine product, it need not be wrapped in toilet paper or any wrapper or material prior to being located in bag as the tied bag efficiently seals the used product, eliminating risk of leakage. Further, since the used product is sealed in the bag it may be hygienically placed in a container specifically designed in public bathrooms, or disposed of within a general waste product basket, bin, or receptacle without risk of contact by user or cleaning personnel to the contents' potential infectious diseases, or the risk of cross-contamination.

The present invention also provides a method for hygienic disposal of a used product comprising the steps of: providing a bag of color plastic imprinted material embedded with fragrance and antimicrobial agents, inserting in the bag a used product, tying two portions extending from the bag to retain the product within the bag, and disposing the tied bag in a receptacle capable of receiving a plurality of ones of the bag with a used product.

The product to be received and sealed in the bag of the present invention may be a used feminine hygiene product, or a used adult incontinence product, or any other individual product where hygienic, discreet disposal is desired.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1-9, a bag 10 of thin plastic material is shown having an open end 11 a and closed end 11 b, and gusseted sides 14 which fold inward between the open and closed ends. The open end 11 a has a die cut and perforated portion 16 along edge 16 a (see FIG. 9) which when removed by the user or manufacturer form two tying or handle portions 18. Portion 16 is removed prior to use of the bag, and may have a hole 20 for hanging such bag on a hook. For example, hole 20 may be ⅜ inches in diameter, and portion 16 may be about ⅞ inches wide and of a length to provide the desired length of tying portions 18. Multiple bags may be heat-blocked along region 22 (see FIG. 9) of portion 16 so as to couple multiple bags 10 together, such as for storage of said multiple bags for presentation on a hook via hole 20. The closed end 11 b is provided by a heat block along edge 11 c. For example, bag 10 may be of 0.001″ (1 mil) thick material, 3½-3⅜ inches in width, and 9¾-10 inches in length. The two tying portions 18 for example may each be about 4 inches in length and each about 1¾ inches in width from the edge of side 14 to the inner edge 16 a parallel to such side edge. The bag 10 may be sized in accordance with the used product to be received in the bag, such that it is limited to receiving but one used product (and other material related to the use or replacement of the product, such as wrappers, inserters, applicators, or the like material). The front 13 a and back 13 b of the bag may be identical except for a shift in a repeated printed pattern of black, white, or color ink or other imprinting material on their outer surfaces. The gusseted sides 14 fold inward along fold 11 d allowing the bag to lie substantially flat, and as best shown in FIGS. 5-7 the gusseted sides expand outward when the bag 10 is in an open position for receiving a feminine hygiene product via open end 11 a, or other product needing hygienic disposal, such as a used adult incontinence product. The sides 14 may be about 2 inches wide when the bag 10 is open, and when the bag is closed, fold 11 d extends inward about 1 inch from its respective gusseted side 14.

Bag 10 is formed of plastic material, such as a base of High Density Polyethylene (HDPE) resin with additional color resin, antimicrobial resin, and fragrance materials. To make the plastic material colored, such as pastel pink color, an HDPE-compatible color resin is used, such as available from A. Schulman, Inc., Akron Ohio, USA. In the case of a pastel pink color for example, the color resin is of a HDPE specified color matched to Pantone Matching System (PMS) # 196.

The antimicrobial resin may be, for example, Polybatch ASX 502 resin, also available from A. Schulman, Inc. Preferably, the antimicrobial resin provides an antimicrobial agent in the plastic material which is EPA registered as being effective against a wide spectrum of microorganisms, such as e-coli bacteria and fungus. Preferably, the color and antimicrobial resins are compounded together, and such compound color and antimicrobial resin products are also available from A. Schulman, Inc. Resulting compounded color and antimicrobial resins may be of 6% Amorphous Silica and 60% Titanium Dioxide.

The fragrance is a poly based material or Perfumery Compound, such as available from International Flavors and Fragrances (IFF), of Hazlet N.J., USA. For example, the fragrance may be IFF catalog number XBF-800230, Sweet Dreams, and such material may be a Poly IFF Concentrate when supplied in pellet form. As other base plastic resins, color resin, and antimicrobial resin components may be used, such components are not limited to those specified herein. For example, the bag's plastic material may be of a base material of combined HDPE and Low Density Polyethylene (LDPE) resins with color compatible resin, antimicrobial resin, and fragrance materials.

Pellets providing the compounded color and antimicrobial resins, fragrance, and base resin(s) are mixed together in a hopper, heated to a point where the material is extruded into a thin film, formed into a tube of specified thickness, width and gusset, imprinted, and die cut into its final shape. When so mixed together, the fragrance material is combined in 2% ratio with base resin(s). The compounded color and antimicrobial resins are combined with the base resin(s) in the hopper to obtain the desired color and antimicrobial strength. The compounded color and antimicrobial resins may for example be in a 5% ratio (e.g., Let Down Ratio) when combined with base resin materials. Other methods for combining the components of the bag plastic material may also be used.

As shown in FIGS. 10A-C, bag 10 is a one-time use bag which a user 24 (illustrated by a hand) can place a used feminine hygiene product 26 (e.g., pads, tampons, sanitary napkins, and panty liners and any wrappers, plastic or cardboard inserters or applicators, associated with the used product or the user's replacement product), or other used individual product where hygienic disposal is desired (e.g., used adult incontinence underwear or pad), ties or knots tying portions 18, and drops into waste receptacle 28 in bathroom or restroom. The knotted tying portions 18 effectively seal in contents 26 reducing risk of contact with germ-laden items. The bag's embedded floral fragrance provides pleasant fresh scent, masking odors, for overall appeal to users. The bag's built in antimicrobial agent inhibits the growth of odor causing bacteria. The color (preferably pastel pink) and imprinted design (preferably of darker reddish pink color and of a floral pattern but other pattern may be used with or without other markings, or text related to bag use) assists in concealment or obfuscate of the bag's content to the human eye. In other words, since the bag's thin material, which enables the bag to be easily handled, tied, and packaged in a dispenser, allows transmission of light there through the pink color (e.g., opaque), both the selected color (i.e., of the bag and imprint) and the imprinted design hinders the ability of the human eye to perceive the contents of the bag which may have pink or reddish blood stains. Use of the bag provides an alternative to flushing in toilet and thereby serves to significantly reduce costly clogs in toilets and plumbing systems from paper and heavy absorbent fiber based items used in feminine hygiene products. The used feminine product need not be wrapped in toilet paper or any wrapper or material prior to being located in bag 10, as the bag efficiently seals the used product, eliminating risk of leakage when sealed properly by tying or knotting portions 18. Furthermore, since the used product is sealed in bag 10 it may be placed in a container specifically designed in public bathrooms, or disposed of within a general waste product basket, bin, or receptacle, without risking contact by user or cleaning personnel to the contents potential infectious diseases. Such specifically designed or general receptacle is of a size capable of receiving multiple tied bags 10 each with used material.

FIGS. 11A and 11B shows a stack of multiple bags 10 in a flat and folded over configuration, respectively. When stacked together and folded over, they may be assembled in a dispenser, such as the portable dispenser shown for example in FIGS. 12A and 12B. In this example, the folded stack is located on a base 30 of dispenser 29, a bottom 31 is folded over the stack and base 30, and then flaps 32 folded form a pocket with the bottom 31. Edge 31 a may be attached, such as by adhesive to base 30 when folded over the base. Flaps 32 may be attached to bottom 31 by adhesive. An opening (or removable perforated portion) 33 enables the user to pull out individual bags from the dispenser 29. Alternatively, the bags 10 may each be folded over and interweaved with each other such that dispensing of one bag exposes (or pops up) either end 11 a or 11 b of the bag underneath from the dispenser opening. A cover 34 may fold over the pocket formed by bottom 31 and flaps 32, having a tongue 34 a which may received in a slit 35 in bottom 31, as shown in FIG. 12A. Opening 33 is shown as a dashed line to indicate that that it lies under cover 34 in FIG. 12A. Dispenser 29 enables multiple bags to be easily carried by a user (e.g., up to 20-30 bags), such as in a purse, handbag, backpack, or pocket. Such enables the bags to be present when the user needs them. The dispenser 29 may be made of cardboard or polyethylene, and is disposable when all bags are used. Portions 16 of the bags may be removed prior to locating the stack of bags in dispenser 29, or removed by the user prior to use of the bag.

Other dispensers may be used than shown in FIGS. 12A-B. As such, multiple bags 10 may be placed in any container in fold-over, flat, or interweave fold-over fashion, which has an opening to individually dispense the bags. Such container may be portable or fixed, such as mounted to the wall or stall of a bathroom or restroom. In the case of a portable dispenser, the opening may be a slit or a fold-over slit, such as typically used in plastic portable tissue packages. Thus, the bag is of a thin material and may be made sufficiently small in size to enable multiple bags to be compact when oriented substantially flat and adjacent to each other in a fixed or portable dispenser in one of at least a stack, folded, or interweave condition.

From the foregoing description, it will be apparent that an improved disposable bag for hygienic disposal of a used product has been provided. Variations and modifications of the herein described bag, dispenser, and method of use, other applications for the invention will undoubtedly suggest themselves to those skilled in the art.
